Even in the magical world of Harry Potter, it’s all about the details.

Every first-year student at Hogwarts School of Witchcraft and Wizardry learns this pretty quickly.

A wobbly wand flick or imprecise incantation can ruin a spell, shattering a teacup that should have turned into a toad. Potion ingredients can be extremely persnickety. And anyone who wants to make friends with a hippogriff had better remember to bow first.

With that in mind — and, of course, anticipating next Friday’s opening of “Harry Potter and the Deathly Hallows: Part 1” — we’ve created a Potter quiz that focuses on the little things. Forget major characters and key plot points; these eight questions take a laser aim at maddeningly difficult trivia.

We’ve plucked one detail from each of the first six books in J.K. Rowling’s famous series, and two questions from the final volume. To pinpoint such trivia, we opened each book to a random spot, and looked for a tidbit on the two facing pages.

If the job’s been done right, acing this quiz should require a photographic memory of the text, or the patience to pan and scan all seven books about the young wizard. (Frustrated? Just pretend you’re a Seeker, searching for the Golden Snitch.)

Are you up to the challenge, Harry Potter fans? We figure you need something to keep you busy over the next week, as you wait for the new movie to arrive in area cinemas.
